MIG welding (like other welding processes) is a skill that takes training and practice in order to master. However, this type of welding is also one of the most precise welding processes around.
To this day, MIG welding is used extensively due to its ability to create quality welds that are strong and beautiful. In this article, we will learn about the different types of MIG welding.

What is MIG Welding?
The machine is known as a metal inert gas (MIG) welder or a flux-core welder. The wire feeder (a spool of wire) holds the wire from the feeder reel or the spool, which is held by a wire feeder reel, which is held by a set of rollers or a set of plates.
How Does it Work?
MIG welding uses a wire electrode to weld two pieces of metal together. The wire can be made out of several different materials, with stainless steel being the most common.
The MIG welder uses two pieces of metal known as leads to transfer the electrical flow from the welding gun into the wire.
The Different Types of Mig Welding
Metal Inert Gas (MIG)
Typically, the MIG gas is delivered to the worker through an air stream that is either a blow-tube (gasman), metal-air bottle, or a glowstick. The MIG wire is usually braided, braid welded, or woven using torch patterns and fluxes, and techniques.
Metal In Gas
MIG welding uses a mixture of argon and nitrogen (two noble gases) as the working gas. Metal oxide (metals) of the metal alloy have to be used as the filler material. In the presence of the working gas, metal oxide becomes molten. This becomes the filler material and prevents the metal from becoming molten during the welding process.
Gasless Mig Welder
In a gasless MIG welder, there is no electric or gas source. An electric magnet rotates around the edges of the welding gun, so there are no sparks and no gas being emitted. These are much cheaper to operate than a gas-operated MIG welder.
Wire Feed Welder
The MIG wire feeder is most commonly used to weld aluminum parts. This type of welder uses a reactive gas flow into a coil that is connected to the end of the welder.
The welder uses gas, typically argon, to resist the flow of oxygen and keep the iron from touching the gas in the coils.
Gas Metal Arc Welder
MIG welders usually require the support of shielding gas. These shield gases are similar in nature to the air.
When there is a risk of metal contamination in the atmosphere the shield gas must be used. This gas is usually supplied by a MIG-probe for the detection of metal contaminants.
Variety Of MIG Welding Transfer Types
- Short Circuit transfer
The short circuit transfer (SC) is a variant of the short circuit transfer (ST) that uses a straight electrode with a high degree of current concentration. This has the effect of keeping the heat input from the electrode to a minimum. - Globular Transfer
When you need to weld large, thick, complex pipe, the globular transfer is a great way to go. This transfer type is different from all of the other MIG transfer types because it uses a long, narrow tip to transfer the molten metal from the wire to the workpiece.
This means that you can weld much longer pieces of pipe at one time than you can with any other transfer type. - Spray Transfer
Spray transfer involves the use of a spray nozzle on the end of the wire feeder. This nozzle emits a cloud of shielding gas, which is then “picked up” by the weld pool.
Spray transfer is highly effective but it can be costly. The process incorporates high voltage and argon shielding gas into the mig welding torch. - Pulsed Spray Transfer
Pulsed Spray transfer is a method that helps the operator to produce high quality and high deposition rate welds. Since the wire to be fed into the weld pool is not completely melted before it gets deposited as the electrode wire, it is of a larger diameter than the wire that comes out of the nozzle.
FAQ
What Type of Welding Is MIG?
What type of welding is MIG? The act of MIG welding is referred to as MIG or magnetic flux-core welding. Magnetic flux welding is one type of MIG welding. Magnetic flux welding has four types of welding, depending on the material of the joint being welded:
What Are the Basics of MIG Welding?
What are the basics of MIG welding? MIG Welding is an excellent welding technique that produces a solid bond between two metals. As with the older welding techniques, it is important that both surfaces are uniform, or the bond will not hold.
Conclusion
We hope you enjoyed this article as much as we enjoyed writing it. We discussed what MIG welding is and the different types of MIG welding. We also went over the variety of MIG welding transfer types. As you can tell, MIG welding can be both fun and productive as long as you know the right welding method to use.
